| Abstract: | In view of that problem of frequent abnormal fluctuation of the thermal resistance temperature signal of the seawater plant, analyze the causes of the fluctuations in the measurement of the thermal resistance temperature from the aspects of the component itself, the thermal resistor three-wire system, the instrument measurement loop and the DCS receive side configuration, and introduces some practical measures to eliminate or reduce the interference in the field, for the reference of the peers. |
